7202LA12J8

Overview

The Renesas 7202LA12J8 is an asynchronous FIFO memory device with a storage capacity of 9K bits, organized as 1K words by 9 bits. It supports unidirectional data transfer at a maximum clock frequency of 50MHz with a typical access time of 12ns. The component operates on a single 5V supply voltage ranging from 4.5V to 5.5V and draws a maximum supply current of 80mA. It features retransmit capability and is housed in a 32-PLCC package.

Feature Summary

• Asynchronous operation for independent read and write clock domains
• Retransmit capability for reliable data handling
• CMOS technology for low power consumption

Applications

• Data buffering between different clock domains
• Interface bridging in high-speed digital systems
• Temporary data storage in communication protocols

Procurement Notes

Verify the specific suffix J8 confirms the 32-PLCC package and lead-free status. Confirm RoHS compliance and MSL rating prior to ordering. Ensure the supplier provides official datasheets matching the 7202LA12J8 designation to avoid confusion with similar variants like IDT7202LA12JG8.

Selection Notes

Select this part when a 1Kx9 depth is required for asynchronous buffering. The 50MHz speed suits moderate-to-high throughput applications. Consider the PLCC package constraints for PCB layout. Verify that the 9-bit width matches the system data bus requirements without additional padding logic.

Part Context

Part of the Renesas 7200 series asynchronous FIFO family. This series offers various depths and speeds for memory buffering needs. The 7202 variant specifically targets 1K word depth applications. Compatible with standard CMOS logic families for easy integration into existing designs.

Replacement Considerations

IDT7202LA12JG8 is a documented alternate part number for this component. Verify pinout and electrical specifications match before substitution. Other 7202 series parts may differ in speed or package type.
